To aZZ'wim'm itmay concern: end of the anvil-shaft b. Tothe anvil 0 Be it known that I, ARTHUR Lornz, a citiis applied a shuttle 0 containing the re zen of the United States of America, residquir'ed number of type for the language to ing in New York. in the borough of Manbe written, which type are arranged in five hattan, county and State of New York, have rows, one. below another, the shuttle being invented certain new and useful Improveshift-able on the anvil by the same means as. ments in Shift-Key Attachments for Typeheretofore employed in Hammond type- Writing Machines, of which the following writers. As a greater range ofiifting of is a specification. the anvil is required, than informer ma- 10 This invention relates to a shift-key atchines, it is necessary that the capital shifttachment for typewriting machines ofthe key have a twofold lifting motion, one Hammond type, 'the attachment being from the ordinary normal position of the mainly, designed for machines which are key to the second row of the shuttle and a used for the Arabic, Turkish and other orisecond motion for the third row of the enta'l languages, in which the alphabet, shuttle, likewise the figure shift-key repunctuation marks, etc., cannot be brought quires two motions. one for the fourth row within the usual three-line type-shuttles, of characters and one for the fifth row of but in which, for example, five lines of type characters on the shuttle. These two nioare required, andin which machines the tions are controlled as to each lever, the first shuttle-guiding anvil and its shuttle have one by an adjustable stop-screw 8 below the 7 5 therefore to be lifted to a greater numberkey-lever and the second motion by shifting of levels or stages so as to provide for the the key on the key-lever in backward direcincreased number of lines of type on the tion, the key-lever being slotted at e for this shuttle: and for this purpose the invention purpose and a spring (1 being interposed consists of means by which the shift-keys for between the shank of the key and the end of 0 the capital letters and. figures and punctuthe slot, so as to permit the backward shiftation marks are each given two separate ing' of the key on the .key-lever and the lifting actions, thereby providing for four lowering of the same into contact with a shifting motions "om the ordinary position second adjustable screw-stop c. adjacent to of the shuttle for printing the ordinary tho first stop.

Y Referring to the drawings, or represents The shift-key levers are guided in slots 7' ofthe ordinary keyboard for the Arabic or the front key-guiding bar 7'. said slots beother language, a the space-key, a'-- the capiing cxtended'in downward direction to pertal shift key, and a the figure shift-key, mit of the extra play of the key-levers, and

The keyof the keys into said recesses and holding levers I1 b of the capital and, figure shift. thereby the key'in lowermost position when keys are pivoted in the usual manner and it is desired to print a number of letters in 55 connected at their inner ends with the lower either the third or fifth rows, respectively. 0

By the means described, the extra lifting motion required for the shuttles for languages having a larger number of rows of type can be provided for in a comparatively simple and effective manner, and thereby the typewriting machines of this class adapted for the use of the alphabets and other characters of such languages.

I claim:

1. In a typewriting machine, the combination, with theshuttle-carrying anvil and its shaft, of key-levers operatively connected therewith and, provided at'their outer ends with longitudinal slots, keys on said keylevers provided with shanks guided in the slots of the same, means in the path of the shift-key when the same is at one end of its slot, for limiting the downward movement.

3. In a typewriting machine, the combination, with the shuttle-carrying anvil and shaft of the same, of key-levers operatively connected therewith longitudinally-sinftable keys, said keys being provided with shanks guidedin slots of the key-levers, means for lowering each shift-key into two positions,

an intermediate and lowermost position, and springs for returning the shift-keys into normal position.

4. In a typewriting machine, the combination, with the shuttle-carrying anvil and shaft of the same, of a shift-key, a key-lever operatively connected therewith, said shiftkey being longitudinally movable on said key-lever, said key-lever being movable into' an intermediate position and into a lowermost position, a fixed abutment in the path of the shift-key when the latter is in onev position on ,the lever, and a second fixed abutment of different length from the first in the path of the shift-key when the shiftkey is in a different position on the key-lever.

5. In a typewriting machine, the combination, with the shuttle-carrying anvil and shaft of the same, of a shift-key, a key-lever operatively connected therewith, said shiftkey being longitudinally movable on said key-lever, said key-lever being movable into an intermediate position and into a lowermost position, a fixed abutment in the path of the shift-key when the latter is in one position on the lever, a second fixed abutment of difierent length from the first in the path of the shift-key when the shift-key is in a different position on the key-lever, and means for vertically adjusting said abut-' ments.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
